Using such an XML standard is a good prac- tice for human-to-human, human-to-system, or system-to-system data exchanges. It reduces manual work to collect and extract the data of hundreds or thousands of declarations. These last years, some progress has been made to harmonize the most used of these standards, including IPC-1752, IEC 62474, and the IPC-1754: 1. The IEC 62474 Maintenance Team (MT) has created Edition 2.0 to eliminate incompatibilities between IEC 62474 and IPC-1752 2. The IPC-1752 committee authors a unique identifier and authority for the lists pro- vided in the appendices of this standard (RoHS, ELV, REACH, IEC 62474, etc.) 3. All elements in the lists shall be granted a unique identifier under IPC-1752 amend- ment 3 as an optional feature and under IPC-1754 version 1.0 as a mandatory feature, including substances not granted with a CAS number or EC number; this specific substance identifier (ID) shall be granted by the authority of the list But the current or "coming soon" versions (IEC 62474 edition 2, issued beginning of 2019) of those standards still present issues either re- garding the data exchange format of the dec- laration itself, the structure of the lists, or the various data used in the declaration or in the list. Table 2 shows a draft inventory of some of those issues as established by the AFNOR (France) T80A standard committee. Objectives for Product Declarations Reporting Ideally, substances and material product dec- larations could be reported with a single data- exchange format as a standard. This would ensure the same content and harmonization in all supply chains with inter-sector data ex- changes. Also, it would reduce the burden and cost in supply chains and ease the support of such formats by the solutions providers that offer tools and data (regulatory definition, dec- larations for COTS products, etc.). This would be very difficult to achieve considering the strong positions of the sectors and their com- panies that have invested a long time on their standard. Another way consists of continuing harmo- nization and convergence between standards with establishing a common body at the end of Table 2: Main issues with current standards. (Source: AFNOR T80A)
